The new range of UNIFLAIR
ARA
water chillers and heat pumps features state-of-the-art technology to give
maximum reliability, safety, quietness of operation and respect for the environment.
1)
RELIABILITY:
Trouble-free operation of Uniflair precision chillers is ensured by rigorous production
process controls under ISO 9001-certified quality procedures:
•
quality control of components;
•
pressure testing of refrigerant and water circuits;
•
testing of current absorption and IEC safety testing;
•
calibration and testing of instruments and safety devices;
•
final testing of unit under operating conditions
2)
ACTIVE SAFETY:
UNIFLAIR safety and control systems have a supervision and prevention function
with:
•
automatic blocking of components in dangerous conditions;
•
indication of function status; reading and continuous display of circulating fluid temperature;
•
management of compressor start-ups to reduce excessive switching on and off
•
compressor start timing to reduce total unit start-up current
•
indication of anomalous function conditions and/or alarms.
3)
PASSIVE SAFETY:
The essential functions of UNIFLAIR chillers are protected against anomalous
function conditions and potential damage with:
•
high and low pressostats on the refrigerant circuit (HP with manual re-set)
•
safety valve on the high pressure refrigerant line
•
anti-freeze protection to prevent freezing of the evaporator, pump and tank
•
compressor motor electrical protection
•
standard differential flow gauge
•
water circuit safety (with optional pump group)
•
compressor crankcase heater (standard on free-cooling and heat pump versions).
4)
PERSONAL SAFETY.
The design and cabling of all UNIFLAIR chillers conforms to IEC electro-
technical norms. Electrical panels have auxiliary 24V circuits and are equipped with:
•
general switch and door lock switch;
•
automatic circuit-breaker switches;
•
double protection panel on fan compartment.
The fans are protected by an external metal grille which conforms to applicable safety norms.
